A big boo boo for Mac version 1.2. I had released it to fix a major bug in the search display, which was crashing the app for some users. However, in rushing out the fix, I had accidentally introduced a bug into the Save feature. Please do not update to v1.2 until v1.2.1 has been released.
I have already submitted the patch to Apple with a note to expedite the review, so hopefully you will get it soon. Sorry for any inconvenience, and I’ll be stepping up the quality controls in the future. If anyone wants a part time job doing software testing for Decked Builder, just drop me an email.
